The main aim of landing the probe is to explore comets as they may hide secrets about nascency of Solar System. According to scientists, comets do hide those secrets.

This is how it looks like

The probe had to attach itself to the comet’s surface, but during the landing it bounced and landed at an angle in the dark. It had been working for 60 hours before its battery ran out of energy. But today it revived and sent signals, as well as 40 seconds worth of data.

Some data shows the comet could have woken up earlier but was unable to connect to Rosetta. Project manager at the German Aerospace Centre, Stephan Ulamec, said:

Philae is doing very well. The lander is ready for operations

Nowadays, the comet is 300 million miles away. Jean-Jacques Dordain, ESA director general, thinks that it is a ‘big step for human civilization.’
